In addition to brass and aluminium there is now also CUPHIN®. Peterseim is the first company to be successful in drawing and subsequently processing CUPHIN® tubes
Do you know of CUPHIN®? CUPHIN® is the brand name for a metallic alloy with unique properties which are immediately predestined for applications associated with drinking water. This is because CUPHIN® is an alloy consisting of copper, zinc and silicon (CuZn21Si3P), which is completely free of lead and other toxic elements. Thus, this material is a real milestone on the way to lead-free pipes for applications associated with drinking water.
What is more, CUPHIN® has the advantage of a particularly high copper content of 76% which effectively prevents the multiplication of bacteria and other microorganisms. In some states of the USA, the use of pipes made from lead-free materials for new drinking water installations is already obligatory today. At the latest in 2013, when the limit value for lead in drinking water will be reduced from 25 to 10 micrograms per litre by the new EU drinking water directive, traditional materials containing lead will have to be replaced with lead-free materials.
